are loom (oh .attached a needle i of; the loom-ha and locate the eyes thereof in position for the drawing-in device; 8 is the screw which separates and feeds the warp-threads into proper position to be caught by the draw ing-in device a. The reed opener e, the' worms 11 and warp-thread separating screw '8, are all supported upon extensions of or brackets upon the traversing carriage A, and normally move with it. W, the frame which supports the warpclamps w w and this warp-frame W is fed or adjusted independently of and differentially to the movement of the carriage A, by means of a wornrwheel 7' which engages a rack on a bar F attached to the frame XV; The worm f is turned by an engaging. pawl which is connected with a rod .f which latter is callscd: to reciprocate by means of a cam on the feed screwshaftof the carriage A. In this machine the end of the shaft of the feechscrew s op posite to the driving mechanism, is supported in a hinged bracket B which may be swung upward upon its pivot 33 to aiford ample space'for inserting and removing the harnesses and their feed-worms i. This bracket B is attached to-the standard B. The detached heddles (1, shown, are intended to be hung upon the warps when in proper positionin the loom, and to serve as dropbars to operate a stop-motion whenever a warp-thread breaks. In the'inclined reservoir.R.'the drop-heddlesd are placed ina compact mass where they are supported by external contact or engagement only, with a weight r back of themto serve as a follower to press the series of heddles forward against the front end of the reservoir. In the botv tom of the reservoir in line with the inner surface-of its front wall is a narrow slot, just large-enough to permit a single perforated heddle to pass through, and this front wall of the reservoir is provided with a slot of a width about equal to the cross-sectional diameter of the eye or perforation in the heddle cl. In front of the forward end of the reservoir and extending vertically from I the top thereofidqwnward to a point a little below the plane in -which the drawing-in device reciprocates, is a ;.guide-way. formed back of the, two plates 9,, g, for a sliding piece t, which may be called a heddle transferring device. This'tra'nsferring device is made up of two parts, one part provided with tongues 2' along each edge, which are engagedby and s'lldein" grooves g back of the guide plates 9, g (see Fig. 9), and another part t, of a width less than the slot between the inner edges of the guides. The partt is hinged to thepart t at t, and theformer has a superposedarm-t hinged there-' to at t The part t is held normally in v the same plane with the part t and tin a. --parallel plane, by a spring twhich is secured at one end to the part t, and its other or free end bearsupon the arm t. The porto the collar 6, the end of a screw t which I passes through the arm t and the collar t projects a little beyond, the surface of the collar, when the parts i 253 are parallel. The

movement of the arm 1 upon its hinge 6 away from the part 15 is limited by a stopscrew 25, which passes loosely through a hole in that arm and is secured in the part t". The[transferring device 15. caused t9 reciprocate in the grooves by means of a lever L pivoted at Z to a standard B, which lever is caused to tilt thereon by a rod Z which connects one end of the lever L with a crank-wheel b This wheel 5 is support ed on'a stud b secured in a bracket 7) which projects upward from the carriage A, and. it is driven by an attached gear 6 which meshes witha gear 5 on the shaft 12*. The device tis connected with the opposite endof the lever L by a link Z the lower end of which is pivoted to a block Z secured to the part if of the transferring device, which will slide up and down invtlie guide-way when the lever L is tilted. When the device If starts down the guideway, the projecting engaging devices 15 i will, by the action ofthe spring 25*, be forced successively into the short plate or finger t projecting at one side of the arm t; then as the transferring devicest, t continue their downward move ment, the finger t will pass down through the opening giand the safety catch 17 will I be pressed throu h the collar t and bear upon the back p ate of the guide-way, in positionready to engage the heddle which is being transferred, should the collar F he accidentally disengaged therefrom. Below the opening 9 a suitable groove g is made for the finger t in-the inner edge of the guide pieceg, to hold that finger down until the eye of theheddle which is being transferred is placed accurately in the path of reciprocation "of the drawing-in device a,

whichis the position shown in Fig. 4. The

lower end of the guide piece (7 consists of a hinged pieceg in which the groove 9'' is gradually diminished until it ceases near tel the-point of the iece g,

which is held down uponthe back 1 ate of the ids-way by a" s ring g Conse uentl'y,ast etransferring' 25 starts up the ride up; on to piece g'7', and thereby the inclined outer surface of arm t and partl and thus withdraw the from the eye of em an aging pieces t, t a, he dle d.

The particular form of reservoir or holder 'for. the heddles d' is not material, so long as it retains'them in a substantlally compact mass and in a manner to permit a single heddle" at a time to be separated from the mass.
